Abstract
Un système de commande pour un système de transmission hydrostatique peut comprendre un circuit de pompe de charge hydraulique (300) ayant une charge hydraulique et un réservoir (302). La pompe de charge hydraulique (304) peut être en communication fluidique avec le circuit de pompe de charge hydraulique (300). Une conduite de dérivation (312) peut s'étendre jusqu'au réservoir (302) à partir d'une jonction entre la pompe de charge hydraulique (304) et la charge hydraulique. Une soupape de dérivation de charge (310) peut être disposée pour commander l'écoulement à travers la conduite de dérivation (312). Le système de commande peut comprendre un dispositif de commande (314) configuré pour déterminer un ou plusieurs paramètres de fonctionnement pour une machine de puissance (200) et commander la soupape de dérivation de charge (312) pour permettre l'écoulement à travers la conduite de dérivation (312), de la pompe de charge hydraulique (304) au réservoir (302), sur la base des paramètres de fonctionnement déterminés pendant une opération de démarrage.
